Breeding the Steel Blue Killifish
Breeding Steel Blue Killifish is a semi-annual process that can be a satisfying experience for hobbyists who are keen on observing innate behaviors and increasing their population through reproduction.
The semi-annual strategy means the egg can survive a period of drying and still remain entirely healthy when permanently submerged. These submerged eggs hatch within 2-3 weeks, depending on the water parameters, especially the temperature.
Breeding Setup
Create a separate breeding tank equipped with fine-leaved plants like Java moss for breeding or killifish spawning mops to provide suitable spawning sites and refuge for the eggs. Setting up the aquarium and managing all the parameters for semi-annual breeding is important.
Pairing
Introduce a compatible breeding pair into the breeding tank, guaranteeing that both male and female are in optimal condition and displaying breeding colors. Observe their behavior to indicate courtship and semi-annual breeding activity.
Spawning Behavior
During courtship, males display bright colors and perform elaborate mating displays to attract females. (Yes, the female killifish often show their preference for specific male mates based on their health profile and display strength).
Once the female is receptive, the pair will engage in a brief spawning ritual, during which the female releases eggs while the male fertilizes them externally.
Egg Collection
After spawning, carefully remove the adult fish from the breeding tank to prevent egg predation and ensure a successful Fundulopanchax gardneri breeding process. Gather the sticky eggs using a soft-bristled brush or carefully cut sections of the spawning substrate and transfer them to a separate rearing tank filled with aged water.
Fry Rearing
Blue Lyretail fry is relatively independent and can be raised on a newly hatched brine shrimp or commercial fry food diet.
Extra tips: Maintaining pristine water conditions and providing gentle aeration are equally essential parts of raising killifish fry.
